Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

[Repro] [4.8] Material Graph Doesn't Refresh Inputs Until A New Node SI

The video here should show the problem: https://www.youtube.com/watch?v=5IcEE5Pg9Vg

Notice how the 'Add' Node doesn't change as I add inputs to it. I have to actually add or delete a node in the graph to force it to re-draw and update the display of it's name.

Previous to 4.8, the node would refresh as it was hooked up.

Hi guys, this issue still occurs in 4.10 and 4.11.

If you right-click and 'preview' a node, it won't show you it's previewing until you create a new node. if you stop previewing, you have to create a node to force-refresh the graph again. There still appear to be some edge cases where this happens.

Hi Eric, this seems to have been repaired in 4.8 Preview 3, but there is still an issue with 'Previewing'.

If you Right click and start 'Previewing' on a node, then stop previewing, the previewing text remains on the node until you force a graph refresh (e.g. by creating a node or something).

There might be more breaking changes too... I'll keep checking!

Hi -

It looks like this issue has been fixed in the most recent version of 4.8 currently in testing. Assuming all goes well, it should be corrected in the next release of 4.8.

Hi Eric, this is an issue again in the 4.8 release. If you right-click and preview a node, then stop previewing that node, it will still say 'previewing' underneath and the node will be huge.

This doesn't go away until you add a new node.

Hi TheJamsh -

I am uncertain why this regressed but it is fixed internal in the 4.9 Branch as well as Master Branch. I will watch it as we move closer to Previewing 4.9 and make sure that it doesn't regress again.

Thank You for the Report -
